Internet Archive changed thier deriving (file processing software). In the previous version such as Moby Dick ( https://archive.org/details/moby_dick_librivox ) the zip file was listed separately in the Download Options and a zip file existed on the page.
Thank you so much for taking the time to reply, David. I tried hovering over "64KBPS MP3" but no link appeared. Perhaps it's because I'm using a Mac???? But the two options to the right of Show All at the bottom of the download option list did work. I now have access to all the readings and am ecstatic.
